| What's up with lousy bass on classic rock recordings? Many rock recordings of that era are quite poor - others are quite good. But yea, lots suck. Many many reasons, one famous one being that several of them were going deaf with traditional old male hearing loss, accelerated by their jobs. Pete Tows... | |
| Ray Charles - "Rap is not music" OTOH Paul McCartney gave a really eloquent explanation of how musci can be modulated in frequency (melody) or time (beat) - and how Rap modulates time - not unlike many classical examples. he drew a lot of parallels to timing changes in classical... | |
| New to vinyl question While jason_b is in fact pointing you to the root of many analog evils, i think you are simply hearing the bad quality of most pressings, especially after much use. Sorry, but unless you spend a mint and buy all new, specialty pressings, really g... | |
| Why don't higher end amplifiers come with a separate power chassis? I design power amps. Simple: cost. The added chassis adds a LOT of cost that could be invested in more important improvements. And it hits again raising shipping costs, also a LOT. The advantages can be minimized through shielding of the only n... | |
| How long does it take a decent quality speaker to "wear out"? Eric gave a good technical answer above (and i agree). For some practical data points, i'll venture that i had a pair of Boston A40s in the basement where the surrounds turned to dust with minimal use an 10-12 years - fast. One of my main pairs o... | |
| Not sure what to think or do... Agree - at a high level anyway- with Holmz. regardless of whether there is a benefit to break-in over time, for electronics, it's icing on the cake. I design the stuff. I hear brand new equipment literally all the time. Its fine. Maybe not optima... | |
| USB yet again asynchronous USB is the only protocol synchronising the server’s and dac’s clocks Confused. Can you explain how does an asynch protocol synch two clocks? Hint: it doesn't. AES/EBU may have better noise rejection but has imbedded clock signa... | |
| Simplest Linear PSU? In my understanding, source components for obvious reasons require the most silent power supplies. Absolutely. I go nuts getting really quiet power for moving coil RIAA phono stages. Think about the impact of even a small amount of noise on som... | |
| Simplest Linear PSU? @clustrocasual So many things to unpack. Look i dont really care what you believe, but i want you to understand, and every reply proves more and more that you are not following my points. 1. I don’t like the sound of SMD components, so seek t... | |
| Simplest Linear PSU? @lewm Regulation, if perfect brings noise to zero. Nothing in this world is perfect. Most regulators generate high frequency noise which can have nasty audible effects (likely beats, but it really doesn't matter - they do). I agree that overal... | |
| Simplest Linear PSU? I should add that the link above describes what appear to be very well thought out supplies, at a not-insane price considering what's inside them. I pay little attention to the stand alone LPS market since i design LPSes for use within products. ... | |
| Simplest Linear PSU? I am a fan of small chokes to eliminate the HF noise generated by most series regulators. | |
| Simplest Linear PSU? Transformer, Bridge Rectifier and filter caps..... yes, that's the simplest but likely not the best. For constant current draw stuff, multiple filter stages can be very very good, and sound remarkably right. but for anything requiring specific... | |
| Simplest Linear PSU? Guys - the amazing level of confusion continues, post after post. The OP asked about power supplies that were made with SMDs. Maybe he mistyped, maybe he has no idea what he’s typing, but he did. SMDs are surface mount devices. Note this means th... | |
| Simplest Linear PSU? SMD, not SMP = Surface Mount Devices THT means through-hole devices often the same devices, different leads. Which is why the criticism is misplaced, IMO. There are bad components of all types. And also good ones. On the topic of SMPS (switc... |
